Infura Development Tutorials, Guides & Insights

Before diving into code examples, it's important to understand the core differences between Etherscan and Infura.

• Etherscan:
• Primarily a block explorer and data provider. It offers read-only access to Ethereum blockchain data such as transaction histories, balances, token transfers, and more.
• Does not allow real-time interaction with the blockchain (e.g., sending transactions).
• Ideal for querying historical data and performing analytics on blockchain data.
• Infura:
• Provides full node access to the Ethereum network, allowing developers to interact with the blockchain in real-time.
• Supports read and write operations, such as sending transactions, deploying smart contracts, and interacting with dApps.
• Best for applications that require real-time interaction with Ethereum, such as decentralized apps (dApps).

This output is the token balance in the smallest unit (e.g., Wei for Ether or the smallest denomination for the token), and you can convert it to the token’s base unit if needed.

Deploying smart contracts is a more advanced topic, but here’s an example of how you can use Ethers.js with Infura to deploy a smart contract:

First, you need to install Ethers.js, a library for interacting with the Ethereum blockchain.

Run the following command in your project folder to install it:

• Website: Tenderly

• Description: An open-source blockchain explorer for Ethereum-based networks.
• Key Features:
• Provides a user-friendly interface for exploring blocks, transactions, and tokens.
• Supports custom networks and sidechains.
• Allows token holders to track token balances and transaction histories.
• Easy to deploy and customize.
